Abstract (en)
[origin: WO2014106551A1] The invention relates to a hydraulic connecting bush (10) for connecting hydraulic lines (52, 54, 73, 74, 92, 94) for hydraulic circuit-breaker drives (98), comprising a hollow cylindrical main body (12, 60, 77) having at least two annular grooves (14, 16, 62, 64, 78, 79), which extend circumferentially on the outer cylindrical surface of the main body and have sealing rings (18, 20, 66, 68, 80, 81) inserted therein, wherein the main body (12, 60, 77) is made of a material having a first modulus of elasticity. The hydraulic connecting bush (10) is designed to be inserted in an overlapping manner in hydraulic lines (52, 54, 73, 74, 92, 94) to be connected that are in contact with each other at end faces of the hydraulic lines, the hydraulic lines being made of a material having a second modulus of elasticity, wherein a gap is formed between the main body (12, 60, 77) and the hydraulic lines (52, 54, 73, 74, 92, 94), such that, if the modulus of elasticity of the first material is less than the modulus of elasticity of the second material and an internal pressure is applied, the main body (12, 60, 77) is expanded more greatly than the hydraulic lines (52, 54, 73, 74, 92, 94) and thus the gap provided for technical reasons is closed in the region of the sealing rings. The invention further relates to a hydraulic connection (50, 72, 96), comprising an aforementioned hydraulic connecting bush (10). And the invention further relates to a hydraulic connecting plug (100, 120) for closing an open hydraulic line (102).
